Call of Duty: Advanced Warfare is a 2014 first-person shooter video game published by Activision.The eleventh major installment in the Call of Duty series, the game was developed by Sledgehammer Games for PlayStation 4, Windows and Xbox One, while High Moon Studios developed the versions released on PlayStation 3 and Xbox 360, and Raven Software developed the game's multiplayer and the Exo ...
In mathematics, a concave function is one for which the value at any convex combination of elements in the domain is greater than or equal to the convex combination of the values at the endpoints. Equivalently, a concave function is any function for which the hypograph is convex. The class of concave functions is in a sense the opposite of the ...
The bivariate normal joint density is quasiconcave. In mathematics, a quasiconvex function is a real -valued function defined on an interval or on a convex subset of a real vector space such that the inverse image of any set of the form is a convex set. For a function of a single variable, along any stretch of the curve the highest point is one ...
Convex optimization is a subfield of mathematical optimization that studies the problem of minimizing convex functions over convex sets (or, equivalently, maximizing concave functions over convex sets). Many classes of convex optimization problems admit polynomial-time algorithms, [1] whereas mathematical optimization is in general NP-hard.
In computational geometry, numerous algorithms are proposed for computing the convex hull of a finite set of points, with various computational complexities . Computing the convex hull means that a non-ambiguous and efficient representation of the required convex shape is constructed. The complexity of the corresponding algorithms is usually ...
WASHINGTON (Reuters) -A 97-year-old judge who was suspended from a U.S. appellate court last year after being accused of unfitness due to cognitive and physical impairment related to her age lost ...
Convex cone. A convex cone (light blue). Inside of it, the light red convex cone consists of all points αx + βy with α, β > 0, for the depicted x and y. The curves on the upper right symbolize that the regions are infinite in extent. In linear algebra, a cone —sometimes called a linear cone for distinguishing it from other sorts of cones ...
In convex geometry and vector algebra, a convex combination is a linear combination of points (which can be vectors, scalars, or more generally points in an affine space) where all coefficients are non-negative and sum to 1. [1] In other words, the operation is equivalent to a standard weighted average, but whose weights are expressed as a ...
